• 教大家用 Hedy 编码
  • JOSHUA ALLEN HOLM

Hedy is a new programming language designed specifically for teaching people to code. What makes Hedy special is its notion of “levels” that start with the most basics concepts and gradually introduce new features that eventually become more Python-like. Hedy is not designed to compete with languages designed for real-world projects. It is 100% focused on teaching.

• Pyodide 分解 + 0.17释放
  • MOZILLA.ORG

The Pyodide project consists of CPython 3.8 compiled to WebAssembly so that Python can run in the browser. Originally developed by Mozilla, Pyodide is now a fully independent project. The latest version 0.17 brings asyncio support and error handling, as well as other improvements.

(是也乎:

嗯哼 WSAM.py 来了.

function jsfunc(array) {
  array.push(2);
  return array.length;
}

pyodide.runPython(`
from js import jsfunc
from pyodide import to_js

def pyfunc():
  mylist = [1,2,3]
  jslist = to_js(mylist)
  return jsfunc(jslist) # returns 4
`)

呃...真的要这么来写 Py ?

• PEP 563 基于字符串的默认类型注释 延迟到 Python 3.11
  • PYTHON.ORG

The Python steering council has decided to roll back changes that made PEP 563’s string-based type annotations the default in Python 3.10. The PEP’s default change is now slated to roll out in Python 3.11.

• PyPy 用 Graphviz 的一些方式
  • CARL FRIEDRICH BOLZ-TEREICK

Graphviz is an open-source graph — or, network — visualization tool. You can use Graphviz to visualize the structure of your applications and programs, and it’s a great way to better understand how code works. In this article, you’ll learn how PyPy uses Graphviz to visualize everything from control flow to parse trees. While the article doesn’t include any source code, there are a number of illustrations and links to whet your appetite and point you to more information.

• For-Else: Python 中一个奇怪但有用的功能
  • YANG ZHOU

Python for loops have an unusual feature: they support an else block that only executes if there is no break in the loop. The pattern isn’t used very often with the argument against it being that it is a bit weird and potentially difficult to understand. But there may be times when for/else makes sense. This article presents three situations where for/else is useful and argues that, in these situations, the pattern makes the code more readable.
